"How can a 40wt tube amp give better bass than Krell 450 mono's"
Perhaps its how you define 'bass', perhaps its a personal preference for a 'fuller' sound as opposed to a 'tighter' sound. Perhaps its just plain electrical synergy with your speakers.
I have noticed over the years that in gereral there seems to a correllation between equipment which produces 'tight bass' and produced thinner, more ascerbic mids and highs, which can be described as airy or bright depending on you preferences for one or the other. I've always suspected, apart from plain old synergy, it was due to the way that rise and decay times were treated in the amp - that is the methodology used to get tight bass was as much due to a shortening of the decay time of a signal as anything else and the warmth of tubes was due to a less sharp rise time.
I'm still looking for a tube or ss amp which has the best of both designs, that has warm, full, tight low frequencies with natural mids and highs allowing for great detail with no thinning or brightness. I used to feel like Diogenes til one day the wind blew out the lamp. :-)
